Natural convection in a square enclosure having two wavy vertical walls is studied. An enclosure is filled with fluid-saturated porous media. A cavity is heated spatially on bottom wall while remaining walls are maintained at lower temperature. The objective of this study is to examine the flow field, temperature distribution and heat transfer inside the cavity when values of Darcy number, Rayl...
In this study, the homogeneity of the continuum model of a fixed bed reactor operated in steady state and unsteady state systems for lean CH4 oxidation is investigated. The steady-state fixed bed reactor system was operated under once-through direction, while the unsteady-state fixed bed reactor system was operated under flow reversal. The governing equations consisting of mass and energy balan...
The transient thermoelastic response of thick hollow cylinder made of functionally graded material under thermal loading is studied. The generalized coupled thermoelasticity based on the Green-Lindsay model is used. The thermal and mechanical properties of the functionally graded material are assumed to be varied in the radial direction according to a power law variation as a function of the vo...
The paper presents the problem of steady-state longitudinal-radial vibrations an elastic hollow cylinder with a viscoelastic coating. properties coating change along radial coordinate only and are described by variable Lame parameters density. ends under sliding interface conditions, outer side surface is subject to periodic loads. Within framework model standard body following principle corres...
In this paper, the steady laminar boundary layer flow of non-Newtonian second grade conducting fluid past a permeable stretching sheet, under the influence of a uniform magnetic field is studied. Three different methods are applied for solving the problem; numerical Finite Element Method (FEM), analytical Collocation Method (CM) and 4th order Runge-Kutta numerical method. The FlexPDE software p...
امروزه روش های زیادی برای گرما دادن به فلزات وجود دارد که هرکدام معایب و مزایای خاص مربوط به خودشان را دارند. یکی از این روش ها گرمای القایی است. این روش دارای مزایایی همچون بازدهی بالا، تمیز بودن، سرعت زیاد و قابلیت انجام در خلاء می باشد. گرمای القایی با استفاده از القای میدان های الکترومغناطیسی فلز را گرم می کند. این روش ترکیب پیچیده ای از میدان های الکترومغناطیسی، انتقال حرارت و پدیده های مت...
